But its security still needs furtherresearch. After an introduction to mobile IP, IPSec and the threat to mobile IP security,an IPSec-based mobile IP se-curity architecture is presented in the article. This architecture combines IPSec and some other secure measures withmobile IP so as to give mobile IP stronger security. In the article this architecture is discussed in detail and a methodis proposed to traverse firewall using IKE.展开更多

In this paper, we propose a novel micro-mobile IP handoff scheme, that is the packet loss avoidance handoff scheme. By using an additional cache at the base station and distinguishing packets with packet IDs, the proposed scheme minimizes the number of lost packets during handoff. Network architecture and detailed handoff procedures are given. We also analyze the cache size at the base station, the associated network load with the handoff procedure, and the handoff delay. The scheme is investigated by computer simulations. Simulation results show that the proposed scheme is suitable for environments with fast mobility and frequent handoff.展开更多
